Special Issue Information

Dear Colleagues,

One of the elements determining the sustainable development of civilization is the appropriate quantity and quality of metals used in the construction of new engineering solutions. Due to dwindling resources, producing metals from primary raw materials is becoming more and more expensive for manufacturers and poses an increasing burden on the natural environment. Therefore, it is necessary to effectively replace this type of raw material with the effective use of metal scrap and other secondary raw materials that are carriers of metals, including rare and critical ones. An inherent effect accompanying the production of metals from primary deposits is, among others, gas emissions and the generation of solid and liquid waste. Utilization and recycling of metal-bearing raw materials and other waste is an effective way to minimize the production costs of new products, minimize the emission of harmful substances into the environment and reduce the so-called carbon footprint. This is an activity that is part of the Circular Economy and is related to the recirculation of used products and production leftovers, thus reducing the negative impact on the natural environment. Generally, the processing and utilization of waste raw materials has a significant impact on the natural environment by limiting storage and energy use. By recycling this type of waste, we reduce the number and size of places needed for their safe storage, and when used in metal production technological processes, we provide the necessary energy, either replacing natural minerals or with the material supplementing raw materials.

The Special Issue, "Efficient Utilization of Metal Waste and Other Solid Waste", provides access to the latest, breakthrough technologies in the field of use and utilization of secondary raw materials, and the high substantive level of original scientific articles is guaranteed by a team of reviewers.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In this paper, results of research on the reactivities of selected biomass types considering their application in pyrometallurgical processes of metal production are presented. Walnut shells, sunflower husk pellets and spent coffee grounds were selected as biomass materials. Their use as potential reducers in the process of metallurgical slag decopperisation is an innovative approach to this subject. The thermogravimetric findings show that all three tested biomass types are classified as highly reactive. The time to reach maximum reactivity ranges from 1.5 to 3 min and, the lowest value is recorded for the sample of spent coffee grounds. The sample hold time of two hours enables copper content reduction to approx. 1 wt% for practically all the reducers tested. A longer duration of liquid slag contact with the reducer results in a decreased copper content in the slag to a value below 1 wt%. Copper concentrations of 0.5 wt% and lower are observed with a hold time of 4 h. The preliminary results indicate that there is great potential for the use of this type of material in non-ferrous metallurgy, which may translate into replacing fossil raw materials and thus introducing the principles of a sustainable process in this case of metal production.
